Improvement in fruit-cans



UNITED STATES HENRY OALLAEAN, OE DAYTON, OHIO.

IMPROVEMENT IN FRUIT-CANS.

Specication forming part of Letters Patent No. 118,586, dated August 29,1871.

To all whom it may concern:

Beit known that I, HENRY GALLAHAN, of the city oi"Dayton, county ofMontgomery and State of Ohio, have invented certain Improvements inManufacture of Preservingans, of Which the following is a specification:

This invention relates to the construction and arrangement of the rim orflange at the top of preserving or fruitcans made oi' sheet metal, thatcans may be provided with a groove exterior to and below the mouth ofthe same for the reception of cement, forming a complete open-top can,the ila-ngc of the cover passing over the edge of the can and descendinginto the groove when the can is to be sealed. It consists in formingfrom a narrovT strip of metal, by pressing or swaging, an indented orcorrugated flange or ring, Which, when placed in proper posit-ion belowthe mouth ofthe can and soldered fastthereto, With its en ds joined,constitutes a projection of the top of the can over which the flange ofthe cover may pass, and forms a groove or receptacle, exterior to thecan, for the cement required to seal up the can.

I am aware that cementgrooves have been formed about the mouths ofmetallic cans in a variety of ways-for instance, by folding the edgeofthe mouth of the can itself, as shown in Figures l and 2; again, bycutting acurved strip of metal, Which, Wh en placed upon the can withits ends soldered, forms a flaring iiange, as shown in Figs. 3 and 4,and the plan in common use, bein g to cut from a sheet of metal a roundilat piece, as shown in Fig. 5, which, when formed in a die and solderedtothe can, constitutes the ccment groove, as shown in Fig. 6. Theiirstnamed of these plans is objectionable because it is very difficultto form the groove in the manner indicated. The secondnamed plan isObjectionable, as it is not easy to Work; the strip of metal not beingpressed or sWaged makes it difcult to retain it in proper position Whilebeing soldered on the can. The last-named plan is objectionable onaccount of the Waste of metal and of the expense and labor required inmaking the same.

By my plan an equally good result is attained at a very much less cost,there being no Waste whatever of metal, and there being less laborrequired in making and'applying it. This plan is shown in Figs. 7,8, 9,and l0.

That others may fully understand my invention, the following is aparticular description:

A sheet of metal is first cut into narrow strips. The strips thus formedare pressed or swaged, by the action of proper forming-rollers, dies, orother tools, and corrugated so as to form a concave flange, a section ofwhich is shown by Figs. 9 and l0.

These corrugated strips, made in the manner described, are manufacturedas an article of trade, to be used by the manufacturers ofpreservingcans by placing them around and near to the top of thc can,and then soldering them at the ends and to the can, so as to form a hoopor ring around the top of the can, making a groove for the receptacle ofcement, Sac., as shown in Fig. 6, these corrugated strips beingfurnished and used by the manufacturer at a much cheaper rate than it ispossible to manufacture the circular lianges made solid, as shown inFigs. 5 and 6.

Having described my invention, what I claim as new is- Thehereindescribed corrugated cement-ring, made from strips of metal joinedat their ends, in contradistinction to the solid ring, substantially asdescribed, as a new article of manufacture and trade.
